Stellar Brief: 20. 10. 2026
Today’s standout finding changes the story of PDS 70: the young star is estimated to be 12 to 16 million years old, about three times older than previously thought. Alpha Centauri was the leading Stellarcatalog search query, with 1,537 impressions on October 19.

Звезды | Экзопланеты | Атмосферы планетThis study explores the capabilities of the upcoming Extremely Large Telescope (ELT) and its ANDES instrument in analyzing the atmospheres of young, distant planets similar to Neptune but smaller. By simulating observations of the exoplanets V1298 Tau b and TOI-451 c, researchers demonstrated that we will soon be able to detect water, hydrogen sulfide, and carbon monoxide on these worlds.
The research highlights that by carefully comparing data from when a planet is passing in front of its st...

27. 2. 2026Звезды | Экзопланеты | Коричневые карлики | Формирование планетResearchers have successfully identified 23 nearby young objects, mostly brown dwarfs, that are surrounded by circumstellar disks of gas and dust. By analyzing data from several space missions and ground-based telescopes, the study found that these disks—the birthplaces of potential rocky planets—exist even around very low-mass objects.
Highlights include the detection of ten entirely new disk-bearing candidates and evidence of long-lived accr...
Read article 27. 2. 2026Звезды | ЭкзопланетыThe Sun-like star GJ 504 presents a cosmic mystery: despite being roughly 2 billion years old, it rotates rapidly and possesses an intense magnetic field typical of a much younger star. This study investigates the theory that GJ 504 'rejuvenated' itself by swallowing a Jupiter-sized planet.
By mapping the star's magnetic field and simulating its stellar winds, researchers found that the star's current high-energy state and rotation speed cann...
Read article 27. 2. 2026Звезды | Молодые звездные объектыThis research investigates how young stars grow by pulling in material from their surrounding environment, specifically within the DF Tauri binary system. By using high-resolution observations, astronomers analyzed the primary star in this pair to see if its companion affects how it 'feeds' on gas and dust.
They found that despite being part of a double-star system, the primary star follows a traditional growth model where a strong magnetic f...
Read article 27. 2. 2026Звезды | Экзопланеты | TESS | Красные карлики | СуперземляA comprehensive search of over 8,000 small, cool stars known as mid-to-late M dwarfs has revealed that these stars are the most common hosts for small planets in our galaxy. Unlike larger stars like our Sun, which typically show a clear 'radius valley'—a gap where planets of a specific size are rarely found—these small stars host a continuous range of planet sizes peaking at about 1.25 times the size of Earth.
The study found that rocky 'supe...
Read article 26. 2. 2026ЗвездыThis study examines the atmospheric behavior and chemical composition of five well-known Mira-type variable stars: RY Cep, SU Cam, T Cep, V667 Cas, and OR Cep.
These aging stars undergo dramatic pulsations that create powerful shockwaves in their atmospheres, leading to the appearance of specific emission lines in their light spectra. By analyzing these spectroscopic changes, the research explains how the balance between carbon and oxygen det...

By detecting 216 compact radio sources and tracking the movement of 58 of them over multiple epochs, the study successfully measured their distances and motions.
The findings reveal that the Orion complex spans distances from 380 to 440 parsecs, p...

Using data from the TESS space telescope and the new PLATOSpec instrument, the team identified TIC 147027702 b, which orbits its star every 44 days; TIC 245076932 b, a planet with a notably oval-shaped, eccentric orbit and a 21-day period; and...
Read article 24. 2. 2026Звезды | Экзопланеты | Формирование планетAstronomers have conducted a detailed study of AT Pyx, a young star surrounded by a planet-forming disk located inside a unique environment called a cometary globule. Using advanced instruments like the VLT and ALMA, researchers discovered that the disk is not perfectly circular but eccentric, featuring distinct spiral arms that may be shaped by a hidden planet with a mass anywhere from a fraction of Jupiter up to three times its size.
The stu...
Read article 24. 2. 2026Звезды | Молодые звездные объекты | ЭкзопланетыA detailed survey of the young star MWC 480 has revealed a massive disk of dust and gas where new planets are likely forming. By combining data from the ALMA and VLA telescopes, researchers identified a prominent dust ring located 95 astronomical units from the star—more than double the distance of Pluto from our Sun. This specific ring contains enough solid material to build the cores of several giant planets.
The study also discovered a new...
